HAT-'s'lzlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 651,560, dated June 12, 1900.

Application filed March 20, 1900. Serial No. 9,674. (.Nomodel.)

To all whom, it may concern/.-

- Be it known that I, SAMUEL L. TAYLOR, a citizen of the United States, residing at Danbury, county of Fairfield, State of Connecticut,have invented anew and useful Hat-Sizing Machine, of which the following is a specification.

My invention has for its object to produce a simple and inexpensive double sizing-machinei. c. a machine at which two operators' can Work at the same time and Wholly independently'of each other or a single operator can Work alone, and which shall cost no more to build and will require no more floor-space than an ordinary single machine.

With these ends in view I have devised a novel hat-sizing machine in which four rollers are so located and arrangedas to form independent sizing-chambers on opposite sides of the machine. I also provide that the pressure of the movable roller upon the roll of hat-bodies in each chamber shall be yielding and self-adjusting-z`- e., lightest at the start and increasing with a regularly-augmented pressure as the size of the roll of hat-bodies decreases-and also provide a positivead j ustment of the movable rollers which will give a non-yielding and hard pressure upon a roll of hat-bodies as the operation of sizing proceeds.

In the accompanying drawings, forming part of this specification, Figure 1 is an end elevation illustrating my novel machine in use as a double machine, large rolls of hatbodies being shown in the sizing-chambers and the movable rollers in approximately the starting position; Fig. 2, an opposite end elevation showing the position of the movable rollers after the operation of sizing has proceeded and the area in cross-section of the sizing-chambers and the size ofthe'rolls ofhat-bodies has been reduced; Fig. 3, a side elevation as seen from the left in Fig. 2; and Fig. I is an endelevation corresponding with Fig. 2, showing one of the movable rollers locked in position to, produce ahard pressure upon the roll of hat-bodies in the chamber, the other movable roller being shown in approximately the starting position.

A denotes framework, which may be of any ordinary or preferred construction, and B a hot-water tank supported thereby. In order jweight 20 is attached..

that the least possible amount of floor-space may be required, I preferably drive the machine from an overhead or an under countershaft. In the present instance I have shown the machine as driven from an overhead counter-shaft by means of a vbelt 10, passing over a pulley 11 on a shaft 12, journaled at the top of the framework and carrying a sprocketpulley I3. v 1

C denotes the upper fixed roller, whose shaft 14 is journaled in the framework; D, the lower fixed roller, whose shaft 15 is also journaled in the framework, and E rollers which I have termed the movable rollers and Whose shafts 16 are journaled in oscillating yokes or frames 17. These yokes which carry the movable rollers may be pivoted concentrically with either of the fixed rollers. In

the presentinstance I have shown said yokes ,Y

as pivoted on the shaft 15 of the lower fixed roller, one end of each frame being pivoted just inside the framework and the other just outside the framework and handles 18 being provided for convenience in manipulation. Each of the yokes is shown as provided with an -angle-arm 19, to which an adjustable I haveshown the weightsas attached `to the arms by means of cords 21; Vbut adjustable sliding weights may of course be used, if preferred. In use the weights are preferably soad] usted as to practically counterbalance the movable rollers.

' 22 denotes springs which may be used auxf iliary to the Weights and which act upon the swinging yokes to place the movable rollers closer to the fixed rollers, thereby contract- ,ing they area in cross-section of the sizingi chambers, as Wlllbe readily understood from 'Fig 4. i

For convenience in description I have designated the sizing-chambers as F, and in said chambers have indicated by dotted lines rolls G of hat-bodies.

It is of course well understood by those familiar with the art that in starting the sizing operation upon a roll of hat-bodies the pressure thereon must be very gentle. In my novel machine the pressure of the movable roller upon the roll o f hat-bodies in each sizing-chamber is produced automatically by means of the springand weight or by the weight alone, if preferred, although the op- IOO , substituted, if preferred.

erator may of courseincrease or diminish the pressure at any time by means of the handle. I have shown coiled springs as used, one end of each spring being attached to the framework and the other to the oscillating yoke. Any other style of spring may, however, be It will be noted that when a roll of hat-bodies is being started in a sizing-chamber, as in Fig. 1, the anglearm of the oscillating yoke stands in a nearlyvertical posit-ion, so that the pull of the weight upon the arm, and consequently the pressure of the movable roller upon the roll of hatbodies in the sizing-chamber, is greatly reduced. Asthesizingoperationproceeds,how ever, and the size of the roll of hat-bodies becolnes reduced the oscillating yoke and movable roller will move up closer to theiixed rollers and the angle-arm will swing downward, it following necessarily that as the outer end of the angle-arm approaches a horizont-al line passing through shaft 15-z'. c., the center of oscillation of the yokethe leverage produced by thel weight, and consequently the pressure upon the roll of hat-bodies in the sizing-chamber, will steadily increase. As the sizing operation proceeds it is sometimes required after several dippings and rcrollings of the roll of hat-bodies to have a uniform hard and non-yielding pressure exerted by the movable roller upon the roll of hatbodies. In order to accomplish this result when required, I provide a rack 23, (see Fig. 4,) ,which may be pivoted to the angle-arm and which is adapted to engage a suitable lug or .catch 24 upon the framework. I vhave shown the rack as provided with a hand-gri p 25 for convenience in operation. In use an operator standing at the left in Fig. 4 would push the rack forward until the sizing-chamber on that side of the machine was reduced sufficiently to give the desired pressure upon the roll of hat-bodies and would then lock the swinging yoke and movable roller in position by engaging the rack with the lug or catch.

The movable and fixed rollers all turn in the same direction. The special mode, however, in which they are connected up is of course not of the essence of myinvention. I have shown shaft 14, carrying the upper xed roller, as provided with sprocket-pulleys 26 and 27 and said shaft and roller as driven by a sprocket-chain 28, running over sprocketpulleys 13 and 26. Shaft l5, which carries the lower fixed roller, is shown as provided with sprocket-pulleys 29 and 30 on one end and on the opposite end with a sprocket-pulley 31. Shaft 15 is driven by means of a sprocket-chain 32,which passes oversprocket pulleys 27 and 30. The shafts 16,which carry the movable rollers, are each provided with a sprocket-pulley 33, one of said sprocketpulleys 33 being of course at one end of the machine and the other sprocket-pulleyat the other end of the machine, as clearlyshown in Fig. 3. These shafts 1G and the movable rollers receivemotion from sprocket-chains 34,

` (See the two one of said sprocket-chains 34 passing over one of the sprocket-pulleys 33 and sprocketpulley 29 and the other passing over the other sprocket-pulley and sprocket-pulley 3l.

In use it does not make the slightest difference, so far as the operation of the machine is concerned, whether it is used as a single or double machine. Unless one side is disconnected 'the four rollers are always turning, the movable roller upon one side ot' the machine forming with the two fixed rollers a sizing-chamber which is wholly independent of the sizing-chamber formed on the other side ot' the machine by the two fixed rollers and the other movable roller. An operator upon one side of the machine may be just starting a roll of hat-bodies with the automatic yielding pressure of the machine, no pressure being applied to the swinging yoke, and an operator upon the other side ofthe machine may be applying a hard and non-yielding pressure to a partly-sized roll of hat-bodies. sides of the machine in Fig. 4.) In using my novel machine a number of hatbodies are dipped, rolled together, and wrapped in a clot-h, and the roll then placed in one ot' the sizing-chambers and operated upon by the sizing-rollers. The roll of hatbodies is unrolled, dipped, rerolled, and rewrapped in the ordinary manner as many times as may be required to complete the operation of sizing.

I-Iaving thus described my invention, I claim- 1. A hat-sizing machine consisting essentially of two fixed rollers and two movable rollers, one on each side of the fixed rollers and each carried by a yoke adapted to oscillate concentrically with one of the fixed rollers whereby two independent sizing-chambers are formed by the four rollers.

2. A hat-sizing machine consisting essentially ot' two iixed rollers and two movable rollers, one on each side of the fixed rollers and each carried by a yoke adapted to oscillate concentrically with one of the fixed rollers, and means whereby the yokes and movable rollers are moved closer to the ixed rollers thereby reducing the area in cross-section of the sizing-chambers.

3. A hat-sizing machine consisting essentially of two xed rollers and two movable rollers, one on each side of the fixed rollers and each carried by a yoke adapted to oscillate concentrically with one of the fixed rollers, and adjustable weights which counterbalance the movable rollers and swing the movable rollers nearer to the fixed rollers.

4. A hat-sizing machine consisting essentially of two fixed rollers and two movable rollers, 011e on each side of the iixed rollers and each carried by a yoke adapted to oscillate concentrically with one of the fixed rollers, an angle-arm extending from each yoke and adapted to stand in a nearly-vertical position when the movable roller is in the starting position an d a weight upon the angle-arm IOO IIO

whereby the pressure of the movable rolleris increased as the angle-arm moves downward.

5. A hat-sizing machine consisting essentially of two fixed rollers and two movable rollers, one on each side of the fixed lrollers and each carried by a yoke adapted to oseillate concentrically with one of the iixed rollers, springs acting to swing the movable rollers nearer to the fixed rollers, an angle-arm extending from each yoke and adapted to stand in a nearly-vertical position whenthe movable roller is in the starting position and a weight upon the angle-arm whereby the pressure of the movable roller is increased as the angle-arm moves downward.

6. A hat-sizing machine consisting essentially of two iXed rollers and two movable rollers, one on each side of the fixed rollers and each carried by a yoke adapted to oscillate concentric'ally with one of the fixed rollers, an angle-arm extending from each of the yokes and means for locking the angle-arm and with it the yoke and movable roller in any desired position whereby a hard and nonyielding pressure may be placed upon a roll of hat-bodies in the sizing-chamber.
